Free ogg vorbis files software for linux

Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel.

This places Vorbis in the same competitive class as audio representations such as MPEG-4 (AAC), and similar to, but higher performance than MPEG-1/2 audio layer 3, MPEG-4 audio (TwinVQ), WMA and PAC.

Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.orgs Ogg multimedia project.

libVorbis is the core Ogg stream / Vorbis engine.

Ogg Vorbis Tag Editor for XMMS is a plugin for XMMS which allows you to edit the tags in ogg vorbis files. The editor is built into the vorbis plugin for XMMS.

Ogg::Vorbis::Header is an object-oriented interface to Ogg Vorbis information and comment fields.

SYNOPSIS

use Ogg::Vorbis::Header;
my $ogg = Ogg::Vorbis::Header->new("song.ogg");
while (my ($k, $v) = each %{$ogg->info}) {
print "$k: $vn";
}
foreach my $com ($ogg->comment_tags) {
print "$com: $_n" foreach $ogg->comment($com);
}
$ogg->add_comments("good", "no", "ok", "yes");
$ogg->delete_comment("ok");
$ogg->write_vorbis;

This module presents an object-oriented interface to Ogg Vorbis files which allows user to view Vorbis info and comments and to modify or add comments.

CONSTRUCTORS

new ($filename)

Partially opens an Ogg Vorbis file to ensure it exists and is actually a Vorbis stream. It then closes the filehandle. It does not fill in the objects data fields. These fields will be automatically filled the first time they are accessed using the objects instance methods. Returns undef if there is a problem opening the file or the file is not valid Ogg Vorbis.

load ([$filename])

Opens an Ogg Vorbis file, reads its information, and then closes the filehandle. Returns undef if there is a problem opening the file or the file is not valid Ogg Vorbis. This is both a constructor and an instance method. The filename is required in constructor context, but should be left out when you call this as an instance method on an object. When called as an instance method, it (re)loads the info and comment data from the file. This can be used to reset the state of the object if write_vorbis hasnt been called. Note that the path parameter is ignored in instance context.

INSTANCE METHODS

These methods may be called on actual Header objects, using the -> operator or indirect objects as you prefer.

info ([$key])

Returns a reference to a hash containing format information about the Vorbis file. Hash fields are: version, channels, rate, bitrate_upper, bitrate_nominal, bitrate_lower, and bitrate_window, length. The bitrate_window value is currently unused by the vorbis codec. You can modify the referenced hash if you want, but I wouldnt suggest it.

The optional key parameter allows you to extract a single value from the internal hash (passed by value, not reference). If the key is invalid, undef is returned.

comment_tags ()

Returns an array holding the key values of each comment field. You can then use these values to access specific fields using comment. This may seem somewhat clunky at first but it will speed up most programs. In addition, it makes it easier to support the Ogg Vorbis comment standard which allows multiple fields with the same key.

comment ($key)

Returns a list of comments given a key. If the key does not exist, returns undef.

add_comments ($key, $value, [$key, $value, ...])

Adds comments with the given keys and values. Takes an array of alternating keys and values as parameters. Keys and values should be valid ascii in the range 0x20 - 0x7D and the key should exclude 0x3D (=). This is a subset of the Vorbis standard which allows this range for the key field and all of utf8 for the value field. This will be fixed in future a release.

If an odd-length array is passed in the routine will fail and return undef. Key and value will be trimmed of characters which do not match the format requirement.

edit_comment ($key, $value, [$num])

Edits a given comment field. The optional num field is used to differentiate between two comments with the same key. If no num is supplied, the first value--as reported by comment--is modified. If the key or num are invalid, nothing is done and undef is returned. If all goes well, the old value is returned.

delete_comment ($key, [$num])

Deletes the comment given by key. The optional num value can be used to specify which comment to delete, given duplicate keys. Leaving num out will result in only the first instance being deleted. Returns undef if key or num are invalid. If all goes well, the value of the deleted comment is returned.

clear_comments ([@keys])

Deletes all of the comments which match keys in the input array or all of the comments in the stream if called with no arguments. Returns undef if any key is invalid, although all keys in the input array up until that key will be cleared. Returns true otherwise.

write_vorbis ()

Write object to its backing file. No comment modifications will be seen in the file until this operation is performed.

path ()

Returns the path/filename of the file the object represents.

OggCarton is a free, open source, home jukebox system that rips, indexes, and manages playlists for Ogg Vorbis music files.
Includes a web server for playing files on your home network. Compatible with existing MP3 files.

jOggPlayer is an open source platform independant Graphical Ogg Vorbis Player. Developed using Java, so if your system has a Java2 VM you can use this app. You can now listen to your Oggs using an app that is NOT bloated. In fact this app/let should be able to run on a web page after you set your java security permissions.
I programmed this because I wanted a Java Graphical Vorbis Ogg player. I did it for myself and thought I would share it with you. My first priority was to get something that worked and looked reasonable. There are still some outstanding issues that I want to fix or work on. Dont expect a WinAMP style playlist, Playlists are harder to be made than the actual player.
Main features:
- plays files from your hard drive or
- plays songs from a URL
- plays streams from jRoar ogg streams (version 1.1 only)
- individual file play or multiple file looping play
- sequential or random play
- in applet volume control that goes to 11!
- visual song progress indicator
- playlist songs have a favourite selection box (version 1.1 only)
- displays ogg file information comments in a mouse-over popup window (song name, artist etc.)
- unlimitted size playlist that can transparently include files and/or URLs
- user selectable directory recursion on file load... just choose a dir from the load file dialog
- can load a file, URL or a whole directory of files on startup
- can save and load your playlist to a file
- can read your m3u playlist for ogg files
- user selectable fonts, colours, and background textures
- needs Java 1.2 or higher
- works behind a proxy/firewall (see the starting documentation)
- PLUS it sounds great!

togg project is the simple Ogg Vorbis tag editor youve been looking for all these years. Its syntax is strongly modelled after id3, the command-line ID3 tag editor, in order to allow for easy mass-tagging of your audio files.
In order to work, it requires the vorbiscomment program from vorbis-tools (see http://www.xiph.org/downloads/) to be installed.
For syntax and usage information, please see the man page togg(1).
Enhancements:
- This release fixes a serious bug that would cause havoc when tagging multiple files.

songanalysis software analyzes a song in WAV, Ogg Vorbis, or MP3 format and produces an output consisting of the volume differential, the relative strength in each frequency band, and the tempo.

This is useful if you want to build something that lets you find out whether you have duplicate files, if you need to find out the tempo of your songs, or if you need to find similar songs according to how they sound.
